The Alpha Automatic 

 Power Spray Outfit 



(PATENTED) 



Fitted with 2-inch or 2'2-'nch Automatic Duplex or Triplex 

 Pump. — Equipped with the New Mechanical 



Automatic Pressure Governor 



Which Insures Safety. Secures Uniform Pressure and Elimi- 

 nates Unnecessary Wear. — No Relief or Diaphragm Valve 

 Required. — Top Guard Rails Fold Up or Can Be Quickly 

 Removed. — Gear or Beit Driven. — Brass Fitted Throughout. 

 THE TWO ESSENTIALS in a power sprayer are a thoroughly 

 dependable engine of ample horsepower and a positive and 

 reliable pressure reg-ulator that will insure uniform pressure 

 and eliminate unnecessary wear. 



THE AVERAGE SPRAY RIG is equipped with a cheap engine 

 and a makeshift pressure relief valve or diaphi-agm. which is 

 exposed to the corrosive action of the spray material, which 

 soon puts it out of commission. 



THE ALPHA AUTOMATIC PRESSURE GOVERNOR with 

 which the Alpha Spray Outfit is equipped is a simple arrange- 

 ment of a combined lever and spring on eacli plunger connecting rod 

 which, wlien the pressure reaches a pre-determined limit, automati- 

 cally discontinues the operation of the pump without interrupting 

 the driving power, again permitting it to resume operation when the 

 pressure falls below the point at which it has been set. 

 THIS INSURES SAFETY, secures uniform pressure, and eliminates 

 unnecessary* wear uio liquid pumped except it passes through the 

 nozzles), the pressure relief is not dependent on the operation of a 

 sluggish or defective relief valve, but is positive and mechanical, 

 thus making it impossible to run the pressure up to the danger 

 point. 



THE POWER PLANT, depending on the size rig. is either a 2^-h.p. 

 or a 31,^-h.p. Alpha Engine, equipped with, a "built-in," gear-driven, 

 positively-timed magneto, requiring no batteries or coil, and is 

 easily started on the magneto without cranking.

"Fruit Marketing of the Pacific North- 

 west" is the titk' of an article by Mr. 

 H. F. Davidson, which is well worthy 

 of the attention of everyone connected 

 with tile fruit industry, for the reason 

 Mr. Davidson has been engaged as a 

 fruit.grower and as a marketer of fruits 

 in the iXorthwest for about thirty 

 years, probably having had a larger 

 and more general experience in the 

 marketing of fruits than any other man 

 in the Northwestern territory. In this 

 article Mr. Davidson brings out very 

 effectively the value of co-operation 

 and orderly control as essential in the 

 marketing if the fruit of the North- 

 west is to be marketed to the best ad- 

 vantage. Mr. Davidson recognizes the 

 fact that there are many marketing 

 concerns in the Northwest in the dilTer- 

 ent districts that have been engaged 

 in Ihe business for years which for 

 various reasons, as shown in his 

 article, have controlled a large tonnage 

 in their respective districts, and fur- 

 ther expresses the opinion that these 

 same concerns will continue to control 

 a large volume of tonnage in the differ- 

 ent districts of the Northwest. There- 

 fore, if the fruit of the NorthwesI is to 

 be marketed at a figure that will pay 

 the grower a satisfactory profit on the 

 investment, it is Mr. Davidson's con- 

 clusion tiiat these marketing concerns 

 must get together an<l work out a prac- 

 tical plan not only for the mutual pro- 

 tection of Ihcmselvcs, but a plan that 

 will pay the fruitgrower at the same 

 time a satisfactory profit. Without a 



satisfactory profit the fruitgrowers of 

 the NorthwesI cannot continue to exist, 

 and if they go out of business there 

 will be no business for the marketing 

 concerns. Mr. Davidson believes it can 

 be done. He also believes that every 

 business man and every bank of the 

 Northwest whose business in any 

 way depends upon the fruit industry 

 should assist in this work in every way 

 possible. 



Fire Blight. — It will not be long be- 

 fore fire blight will begin its work, 

 therefore it seems timely to suggest to 

 the fruitgrowers, at least to those who 

 are not posted, that they take advantage 

 of the present time when they are not 

 busy to learn and ascertain the proper 

 nielhods for control in order to fight 

 fire blight when it begins to show up, 

 because only by drastic work can fire 

 blight either be controlled or elimi- 

 nated. 



The Soiitliern I'liriflc liailwiiy is doing some 

 very valuable work in a way that certainly 

 will be very cfTcrtivc in inducing travel to 

 the Northwest with a view to assisting in 

 upbuilding the Northwest. The Southern 

 Pacific Railway is sending to passenger agents 

 of the various roads throughout the United 

 States very interesting and instruelive letters 

 about the scenery along the Overland Routes 

 from Chicago to the Pacific Nnrthwrst. and 

 also along the line of the Southern Pacific 

 from Pfu'tland to ,San Francisc<t. Such infoi- 

 malion will enaljle the ticket agent to intelli- 

 gently sot forth tlie attractions of the North- 

 west in such ni.'inner as to induce nian>' jjeople 

 to visit the N<n'thw est. In connection with 

 this work Mr. .Tolin M. Scott, (ieneral Passen- 

 ger Agent of the Southern Pacific Railwaj-. 

 states that the Southern Pacific has issued 



some very attractive folders describing the 

 cities, towns and points of interest on the 

 Southern Pacific line from Portland to New 

 Orleans and from San Francisco to Ogden. 

 They are called the "\yayside Notes Shasta 

 Route," the "Wayside Notes Sunset Route,*' 

 and "Waysitie Notes Ogden Route." These 

 I>ooklets can Ije obtained by retiuest from one 

 of the passenger agents of this road. They 

 are beautifully illustrated and will no doubt 

 be good features in showing tip the scenery 

 along the Overland Routes, particularly the 

 Pacific Coast. 



(y)l(t ^ycalhor Freezes Apples. — The very 

 coUl spell covei-ing the entire NorthwesI when 

 nearly every fruit section went to zero, and 

 some sections considerably lower, caught a 

 large quantity of apples on common storage, 

 causing a very heavy loss.
